Aflatoxin M1 Contamination in Pasteurized Milk in Mashhad, Iran

Abstract

The aim of this study was to evaluate aflatoxin M 1 (AFM 1 ) contamination in pasteurized milk samples in Mashhad, Iran. One hundred and ten milk samples from different supermarkets were collected during three months in spring and investigated by Enzyme Linked Immuno Sorbent Assay (ELISA). AFM 1 was found in 100% of the milk samples. About 5.4% of the samples contained AFM 1 greater than the maximum tolerance limit (0.05 μg/l) accepted by European Union. There was not a significant difference among the mean value of AFM 1 in three months.
